x264 Video Codec r1148 for chip x32

latest changes:

- More CABAC and CAVLC optimizations
Simplified function calling for block_residual_write_(cabac|cavlc) and improved sigmap coding.
Tried making 0/1-bit specific versions of CABAC asm, but benefit was minimal under GCC 4.3.
Helped a decent bit under 3.4, but you shouldn't be using such old versions anyways.

x264 Video Codec r1184 for chip x32

20.07.2009

latest changes:

  • New AQ algorithm option
  • "Auto-variance" uses log(var)^2 instead of log(var) and attempts to adapt strength per-frame.
  • Generates significantly better SSIM; on by default with --tune ssim.
  • Whether it generates visually better quality is still up for debate.
  • Available as --aq-mode 2.
